What is ColdCard?

ColdCard is an open-source cryptocurrency hardware wallet that enables users to store their Bitcoins in complete physical security with the option never to be connected to a computer. ColdCard stores the user's seed words in a specialized chip, designed to securely store secrets. Also, all code is open source so the user can compile it themselves. With all these security features and more, Coldcard is truly the world's most trusted and secure Bitcoin hardware wallet.

Why choose ColdCard?

Duress PIN

ColdCard has a nifty security feature - in case a wrong PIN is entered, then the user will be connected to a dummy wallet which is separate from the 'true' wallet storing all the funds. It is up to the owner to put any amount of money into that dummy wallet to make it seem believable.

Extreme Compatibility

ColdCard can work with other Bitcoin hardware wallets thanks to BIP174 which introduces a binary file format that all hardware wallets can use. ColdCard exclusively uses and has been based on BIP174 since its conception.

Secure element for key storage

ColdCard uses a Secure Element to protect its users' Bitcoin. This is possible through a very powerful microchip ATECC608A to safeguard the 24-word seed phrase for the BIP32/BIP39 wallet.

Pricing

ColdCard starts at $129.97.

Reviews

ColdCard is designed to be unhackable. Once anybody uses ColdCard, the only thing that would compromise their funds is if they themselves betray the passphrase to others. It is open-sourced, easy to navigate, and supports other hardware wallets. Its useful features justify its price tag so if you are serious about your digital assets then ColdCard is the best option to go for.
